“…Knaust (2007a) described A. fossulata as a gastropod burrow (fodinichnion). Mángano et al (2005), Carmona et al (2006) and Sarkar et al (2009) interpreted it as a grazing trace (pascichnion) produced by arthropods, annelids and molluscs. Baucon and Felletti (2013b) related Archaeonassa to the locomotion behaviour of gastropods, independently of their feeding strategy.…”

The following trace fossils have been recognised in the Lower Muschelkalk of Raciborowice Gorne (North Sudetic Synclinorium, SW Poland): Archaeonassa fossulata, Balanoglossites triadicus, ?Gastrochaenolites isp., Lockeia isp., Palaeophycus tubularis, Palaeophycus isp., ?Planolites beverleyensis, P. montanus, Planolites isp., ?Protovirgularia isp., Rhizocorallium commune var. auriforme, R. commune var. irregulare, R. jenense, Skolithos linearis, Thalassinoides suevicus and Trypanites weisei. Coprolites and an unidentified trace fossil A are also described. The trace fossils allow the discrimination of five ichnoassociations in the Raciborowice Gorne section: (IA 1) Rhizocorallium- Pholeus, (IA 2) Rhizocorallium-Palaeophycus, (IA 3) Thalassinoides, (IA 4) Trypanites-Balanoglossites and (IA 5) Planolites-Palaeophycus. The Lower Muschelkalk succession was deposited on a shallow carbonate ramp affected by frequent storms. Deposition commenced with sedimentation in a restricted lagoon on the inner ramp with a short episode of sabkha formation. It continued on the middle and outer ramp and then on a skeletal shoal of the outer ramp and in an open basin. Ichnoassociation IA 5 is related to a maximum transgression that commenced with the deposition of the Spiriferina Bed and which probably marked the opening of the Silesian-Moravian Gate. The basin underwent two shallowing episodes, as evidenced by ichnoassociations IA 3-IA 4, resulting in the formation of hardgrounds. Bathymetric changes in the Raciborowice Gorne section correspond well with a general transgressive trend in the Germanic Basin.

“…This ichnogenus has been recorded from Cambrian to Holocene in marine (e.g. Dam, 1990;Uchman, 1998;Uchman et al, 2005;Sarkar et al, 2009), deltaic (e.g. Bann & Fielding, 2004;Gani et al, 2007;Buatois et al, 2008) and non-marine settings (e.g.…”

“…However, Diptera are not present in the fossil record before the Upper Triassic (Mángano et al, 1996). Grazing, feeding, locomotion, and predation are the main ethologic behaviors represented by Cochlichnus (Eagar et al, 1985;Dam, 1990;Netto, 1992;Buatois & Mángano, 1993;Głuszek, 1995;Buatois et al, 1997;Sarkar et al, 2009), being recorded in marine, marginal-marine and continental subaquatic environments, including lacustrine (e.g. Buatois & Mángano, 1993, 1995Gibert et al, 2000;Netto et al, 2009;Uchman et al, 2009), deltaic (Eagar et al, 1985;Melchor et al, 2003) and fluvial deposits (see compilation by (Keighley & Pickerill, 1996).…”

Trace fossils from the Permian Teresina Formation at Cerro Caveiras (S Brazil)

-The ichnofauna of the Teresina Formation from the Cerro Caveiras (Dom Pedrito, Rio Grande do Sul State, South Brazil) is revised in this paper. Bergaueria isp., Cochlichnus cf. anguineus, Cruziana problematica, cf. Diplocraterion isp., Diplopodichnus biformis, Helminthopsis isp., Lockeia siliquaria, Multina arcuata isp. nov., Oldhamia isp., Palaeophycus striatus, P. tubularis, Phymatoderma burkei, Planolites beverleyensis, P. montanus, Teichichnus isp., and Thalassinoides isp. were recorded. Isopodichnus problematicus, Helminthopsis tenuis and Unarites isp., previously described in these deposits are now described as Cruziana problematica, indeterminate molluscan trail, and Multina arcuata isp. nov., respectively. The ichnofauna is composed chiefly of horizontal, simple shallow burrows, with a predominance of feeding structures. Resting, dwelling and crawling structures also occur, as well as indeterminate tiny grazing trails, but are less frequent. Ichnodiversity and intensity of bioturbation are usually low, and P. montanus is the commonest ichnotaxon. The main characteristics of the ichnofauna suggest a marine benthic fauna stressed by salinity fluctuations and resulting in an impoverished Cruziana ichnofacies. The absence of vertical burrows and the common occurrences of monospecific assemblages of Planolites indicate extreme stress events, probably due to the establishment of freshwater conditions. Further studies focused on the ichnological signatures of these deposits will provide more detailed information to improve the current paleoecologic and paleoenvironmental interpretations of the Teresina Formation deposits.

Lower Devonian tempestites in western Yangtze, South China: insight fromZoophycosichnofabrics

A Lower Devonian (Emsian) tempestite in the western Yangtze plate, China, was studied based on ichnological and stratigraphical features. The results indicated that the local tempestite can be grouped into clastic constituent types, which include bottom erosion structures, graded beds, swaley cross‐stratification (SCS), parallel lamination, bioturbation and the new composition Zoophycos ichnofabrics. Five storm sequences and three Zoophycos ichnofabrics (Zoophycos–Chondrites ichnofabric, Zoophycos–Chondrites–Thalassinoides ichnofabric and Zoophycos–Thalassinoides–Palaeophycus ichnofabric) were discerned. It is demonstrated that the Zoophycos‐producers from the complex types of Zoophycos in storm sequences were opportunistic organisms (r‐strategists). This study reveals storm‐generated physical and biogenic structures and textures and provides a good ichnological method to identify storm deposits. Copyright © 2013 John Wiley & Sons, Ltd.
